Find the general solution to the following equation in degrees (find all real number solutions) and choose the correct answer below. 2 sin (3x) -√3=0 Or= = 30° + 360° k I= 60° +180° k 60° +360�

Answers

Answer 1

The correct option is D. 20° + 120°k or 40° + 120°k. This is the correct general solution to the given equation.

The equation 2 sin (3x) -√3=0 can be written as sin(3x) = √3/2

To find the general solution, we need to solve for x in the range of 0° to 360° using the reference angle of 30°. We can apply the formula as shown below: sin(30°) = 1/2sin(60°) = √3/2sin(90°) = 1

Thus, we can rewrite the equation as sin(3x) = sin(60°). This means that 3x = 60° + 360°k or 180° - 60° + 360°k, where k is an integer.

We can then solve for x by dividing by 3. So, x = 20° + 120°k or 40° + 120°k.

Therefore, the general solution to the equation is given by: x = 20° + 120°k or 40° + 120°k, where k is an integer.

Choice A: 30° + 360°k

This is not a solution to the given equation.

Choice B: 60° + 180°k

This is not a solution to the given equation.

Choice C: 60° + 360°k

This is not a solution to the given equation.

Choice D: 20° + 120°k or 40° + 120°k

This is the correct general solution to the given equation.

1.A house worth $250,000 has an coinsurance clause of 90 percent. The owners insure the property for $191,250. They then have a fire that causes $80,000 in damage. How much money will they receive from insurance?

2.A house worth $180,000 has a coinsurance clause of 75 percent. The owners insure the property for $101,250. They then have a loss that results in a $50,000 claim. How much money will they receive from insurance?

Answers

1. Multiply the value of the house by the percent:

250,000 x 0.9 = 225,000

Divide the amount the owner insured by the clause amount:

191,250/225,000 = 0.85

Multiply that by the amount of damage:

0.85 x 80,000 = 68,000

They will receive $68,000

2. Follow the same steps as above:

180,000 x 0.75 = 135,000

101,250 / 135,000 = 0.75

0.75 x 50,000 = 37,500

They will receive $37,500

Answer:

1. They will receive $72,000 in insurance.

2. They will receive $37,500 in insurance.

Step-by-step explanation:

1.Given that the coinsurance is 90 percent.

For the fire that caused a $80,000 in damage, 90 percent of $80,000 will be received in insurance.

90 percent of $80,000 will be received in insurance

90 percent of $80,000 = 0.9 * 80000

= 72,000

Therefore, they will receive $72,000 in insurance

2. The coinsurance is 75 percent, given that they have a loss that results in a $50,000 claim.

they will received 75 percent of $50,000

75 percent of $50,000 = 0.75 * 50000

= 37.500

Therefore, they will receive $37,500

Answers

In linear equation, The sides of the triangle on the drawing should be 6 inches, 8 inches, and 9 inches.

What in mathematics is a linear equation?

An algebraic equation B. y=mx+b (where m is the slope and b is the y-intercept) containing simple constants and first-order (linear) components, such as the following, is called a linear equation.

                           The above is sometimes called a "linear equation in two variables" where x and y are variables. Equations in which the variable is power 1 are called linear equations. axe+b = 0 is a one-variable example where a and b are real numbers and x is a variable. 

A triangle with sides 12 feet, 16 feet, and 18 feet on a drawing where 1 inch = 2 feet.

Then, 1 feet of original triangle = 1/2 inch on drawing.

Now, the sides of the triangle on the drawing are

12 feet = 1/2 * 12 = 6 in

12 feet = 1/2 * 16 = 8 in

12 feet = 1/2 * 18 = 9 in

Hence, the sides of the triangle on the drawing should be 6 inches, 8 inches, and 9 inches..

If the weight of packages is multiplied by 6/5 (fraction) the result is 24.5 pounds. What is the weight of the package (in pounds)?

Answers

The weight of the package in pounds is 24.42 pounds.

According to the question,

We have the following information:

If the weight of packages is multiplied by 6/5 (fraction) the result is 24.5 pounds.

First, we will convert this fraction into a number with a decimal point.

So, we have:

6/5 = 1.2

Now, let's take the weight of the packages to be x pounds.

So, we have the following expression:

1.2x = 24.5

x = 24.5/1.2

(1.2 was in multiplication on the left hand side. So, it is in the division on the right hand side.)

x = 20.42 pounds

Hence, the weight of the package in pounds is 20.42 pounds.

The following cone has a slant height of 17
cm and a radius of 8
cm.

What is the volume of the cone?
Responses

480π
320π
544π

Answers

The formula for the volume of a cone is:

V = (1/3)πr²h

where r is the radius of the base, h is the height of the cone, and π is pi.

In this case, the slant height is given as 17 cm, which we can use with the radius to find the height of the cone using the Pythagorean theorem:

h² = s² - r²

h² = 17² - 8²

h² = 225

h = 15

Now that we have the height, we can plug in the values for r and h into the formula for the volume:

V = (1/3)π(8²)(15)

V = (1/3)π(64)(15)

V = (1/3)(960π)

V = 320π

Therefore, the volume of the cone is 320π cubic cm. Answer: 320π.

Demand occurs at the rate 0.75 clients per hour.
What is the implied utilizati

Answers

Answer:

Step-by-step explanation:

The implied utilization of the resources in the process can be calculated by dividing the demand rate by the total capacity of the resources. In this case, the total capacity is 1.1 + 0.93 = 2.03 clients per hour. Therefore, the implied utilization is 0.75 / 2.03 = 0.369 (or 36.9%).

The implied utilization represents the proportion of the available capacity that is being utilized to meet the demand. In this scenario, approximately 36.9% of the total capacity is being utilized to serve the clients. This indicates that there is still some unused capacity available in the process.

The aircraft carrier and the container ship both took 30 hours to travel their respective distances. If you divide both numbers by 30, you find that their differences is 5. We can tell that the aircraft carrier traveled 450 ÷ 30 = 15 km/hr and the container ship traveled at a speed of 300 ÷ 30 = 10 km/hr. The aircraft carrier traveled 5 km/hr faster. So, we can tell the container ship traveled at 10 km/hr.

As the number of calls made by a cell phone increases, the cell phone bill amount increases. Reset Next

Answers

Answer:

In Option A, we can see that the reverse may not be true as the increase in the risk for lung cancer may not necessarily mean an increase in cigarette smoked in a day. For example, high risk of lung cancer may be due to high exposure to asbestos dust too.

In Option B, again we can see that the reverse may not be true as an increase in the height of an infant does not necessarily mean that the age of the infant is increasing too. For example the infant may have a rapid gain in height even if the age is not increasing as rapidly.

In Option C, too, that an increase in the amount of pollution in a city does necessarily mean that the number of vehicles in the city has increased. For example, this increase in pollution may be due to the establishment of a high pollution causing industry in the city or in it's vicinity.

Likewise, in Option D, an increase in the density of water does not necessarily mean that the concentration of salt in the water has increased.

Only in Option E do we see a possible reverse dependence happening because an increase in the phone bill amount does usually mean an increase in the number of calls made by the cell phone.

So, in the given list of Options only in Option E can we reverse the dependent and independent variables while keeping the interpretation of the slope meaningful.
